Link beween SAP Invoice Number and IDCP Invoice Number

Hello All

We have a plant in Mexico where we are using IDCP to generate internal invoice number. This is the requirement from Mexico Govt.

We are using SAP Invoice numbers in IDCP transaction to generate the internal invoice number.

I am trying to find the relation between IDCP generated Invoice number and normal SAP invoice number.

Is there any table where I can find the link between these 2 numbers?

As all our invoices from Mexico have this number, we are looking the way to track back using this invoice number and find corresponding SAP Invoice number and other documents.

Please let me know if anyone has come across the similar situation.

Thanks

Jayesh
